Please. help with control's search

If you would have asked the question in the article's forum it would have been better.

The word "politics" describes the process so well: "Poli" in Latin meaning "many" and "tics" meaning "bloodsucking creatures."

Hello, my friends!
Got one problem. I need one control for my product:
Something that will allow visual linking between two tables.
For example class diagram in Visual Studio:

or(it would be much more better) in MS Access:
http://www.cyberforum.ru/attachment.php?attachmentid=1978&thumb=1&d=1233315904

I believe, that somebody has already created such control!
I will be very thankful to everybody, who'll answer me Smile | :)

P.S. Sorry for my terrible English Wink | ;)

Try out Flowchart.Net[^]. May be that is something you need.

Thanx, but Flowchart.net is too big and good for me))) And there are no source files for it.

So you are looking for code? If yes then you are at wrong site. Search google.

Google doesn't help. And, as far as I know, this site's purpose is to share CODE between participants. Why do you think i'm at a wrong site?

No, the purpose of the site is to help people write their own code. Not just hand over stuff like a swap meet.

And Google DOES help, if you know how to do research. For example, start by looking to see if any of this stuff[^] will fit your needs.

Partially, yes. So, I want to invite you to SHARE your solution and code as soon as it works, so that others may learn and benefit from it. You're not going to get any money for that, only peer recognition, a few 1-votes and a good, warm feeling inside. Because you helped the community Big Grin | :-D

CP is not the place to order code. We're no take-away chinese, and there ain't no such thing as a free lunch, unless you're a Wall-street-idiot Smile | :)

Back to the point; The component you want is available in the articles on CodeProject. It's not entirely what you want, but close enough. Search for "UML" and the likes Thumbs Up | :thumbsup:

There is a site that is built around that idea solely. It's called Google Code[^].

Thanx a lot! I'll investigate those things and if succeed, put here some of my solutions.

Windows Forms/C# - Controls disappear from Design mode of winform.

Have you used Flowchart.Net?

I need a charting package which should be quite rich in features. Some of the requirements are:
- the ability to create a tree/network diagram
- user can select items in diagram and the items can be wired so that clicking executes my custom code
- user can draw connectors between items and again I need to execute some code in this situation
- items that are shown may be arranged on a timeline (a bit like Gantt-chart)
- items may be arranged on swimlanes
- drag and drop can be used both on timeline and swimlanes

In your opinion do you think Flowchart.Net would be up to these requirements?

Thanks in advance,

Mika

Hi,
I have a strange kind of problem. I never faced it nither heard about it.
All controls are disappeared from Design mode.
Form.Designer.cs is having complete code of control initialization but there is no control in design mode...

I tried to add new controls with same name, it says control already exist.

What is the possible reason of this?
I want to regenerate those old controls kindly help.

Thanks in advance for help.

I have made user controls of all default windows controls e.g. buttons, text box etc. So i make some skinning capability in it and some functionality enhancements.

So now i have a problem. I have an application developed earlier which usage all default windows controls. I want that i place a single component on each form and it replaces the default controls with my controls run time. Mostly i used paint in my controls. All my work is in C# and VS2005.

Please some body help me. And thanks in advance.

That is quite a large undertaking. One in which it would be easier if you just rewrote the application.

Basically, you have to go through the controls on the form and wire up new Paint event handlers from every control type. You'd have to supply painting code for every control your app uses, CheckBox's, TextBox's, Button's, ...

Thanks a lot. It helps me to understand how to implement my situation. I will check it, if it would be done.

In market there are many skinning frameworks e.g. SkinCrafter. we put a control on the form and supply it a skin, and all forms from that application is skinned automatically. Can you guide me of that process. Or suggest me of any tutorial or book which helps me to do so.

Thanks for previous answer and thanks helping me in further in advance.

I just told you how it worked. You go enumerate the form's Controls collection, check the type of control and, depending on the type, use AddHandler to wire up it's Paint event to your own custom paint code.

NazarHussain wrote:

I don't of any skinning tutorials, at least none that show you how to write your own component. Using a third party component, I've seen.

Though, see what you can gleen from this[^]. It's not a good article because it doesn't explain anything about the code or concepts. But, if you can read the code, you might get something out of it.

Then nodes which are not selected, will not be visible. Now originally none of the nodes should be selected and hence all nodes are invisible.

As per the requirement, drag drop a tree view on your form. And in form load event write this:

this.treeView1.Visible = false;

You:
- get a SqlConnection[^]
- define a SqlCommand[^]
- set the sql statement
- define SqlParameter(s)[^]
- and then you execute[^] the command.

As these are very basic ado.net operations, I suggest buying a good book. For example this one seems pretty good: http://www.amazon.com/Beginning-VB-2008-Databases-Professional/dp/1590599470/ref=sr_1_15?ie=UTF8&s=books&qid=1233139704&sr=8-15[^]
